. IPISTON'RING DEVICE.

Specification of Letters Patent.

Patented Sept. 23, 1919.

hpplicaticn led September 1, 1916, Serial No. 118,005. Renewed February21, 1919., Serial No. 223,511.

To all whom 'it may concern f Be it known that I, EMIL. FRANKE, acitizen of the United States, residing at Long Island City, in thecounty of Queens and State of New York, have invented new and useful`Improvements in listoirRing Devices, of which the following isaspecifica tion.

This invention relates to pistr'm ring holding and contracting tools,and has for its principal object the provision of a tool of thischaracter by means of which the 1packing rings of a piston can beeventually eld in a contracted condition during the operation of placingthe piston in the cyl inder.

Another object of the invention resides in the provision of a device ofthis character which will include an adjustable ring embracing stra-p,which Will accommodate itV self to piston rings of various sizes.

With the above and other objects in view which will appear as the natureof the invention isl better understood, the same consists in theimproved construction and novel arrangements of parts which will hereinafter be fully described and particularly.

" brought together.

pointed out in the claims.

In the accompanying drawings, has been illustrated, a sin 4 le andpreferred form of the invention, it eing, however, understood that noliniitationsare necessarily made to the precise structural detailstherein exhiliited, but that changes, alterations and modificationswithin the scope of the claims may' be resorted to when desired levers 1and 2 pivoted at 3, theyr are Figure 1, is a perspectivel view of thetool. Fig. 2, is a fragmentary plan view thereof, showing parts insection.

VFi 3, is a. perspective view of the der` Y tacha 1e sectonof theclamping ring.

The invention ,consists of oom anion e to rock one upon the other aswill bex-under` stood.

The lever 1, is extended ward end of the lever 2, and 1t is providedwith an angular lu'g4, to which one end of a steel strip 5, is rivetedor otherwise suitably secured as at 6.

The said steel strip 5, is provided with a longitudinal series ofapertures 7, which are spaced at equal distances apart.

A heel 8 is provided at the end of the handle 2 and the seid heelrovided with a convexed face best shown 1n Fig. .2. A

ond for-r pin S' is carried by the heel 8 and located neurone endthereof and arranged substantially at an acute angle thereto.

In using the tool the o )erating ends of the `handles l and 2 arehrstscparated so that the spring strip can be freely placed over theiston and around the ring to be contracted). The free end of the ring01'` .spring strip is thenV adjusted relatively of the obtuse angularactuating pin upon the heel of the levert?, when the levers 1 and 2 aredrawn together by the hands of the operator, the said pin will be madeto engage in one of the apertures in the spring strip, and consequentlythe ring will be c0utrncted, carrying with -it the piston ring andthereby permittin the latter to {rcel} enter the en me cylin er.

By provi mg the convexity upon the forward face of the heel 8, andthrough the fact that the pin 8 extends` at an obtuse angle to saidoonvezgity, the free end of the apertured sprin strip, 5 of the section9 will extend substantially at a tangent to the convexity so that thepinB' will be free to immediately pass into an aperture of the strip orsection when the 2 levers l and 2 are In connection with the springstrip mentioned herein I employ a detachable section 9, havingAattaching tongues 10, stamped therefrom and ada ted to be passed into a*corresponding num er of the apertures in the' s ring strip at the *freeend thereof, thus ormlng a continuation of the spring stri andpermitting the device to accommo ate itself to large pistons as will beunderstood. i

The' section 9 is providedwith apertures similar' to apertures'Ihereinbefore described in eonjunctlon'with the strip 5.

What I claim as new is i.

1. A piston ring'eontracting-'device comprisi two hand e levers pivotedtogether at mts between their ends, one of the sei 'levers havin aworkin end portion which is larger t anthe wor ing end ortion of theother lever, the longer lever aving atits end a laterally disposed lugwhich s s aced from the `ad'aeent end of the' sho .r lever, said sho rlever having a convexed heel disposed immediately o poste said lug, apin carried projectin said heel near one end thereof and a ted tooperate in the space between the en s of said lever and the lug, therebeing an unobstructed entrance into the said space beyond the end of theshorter lever, andV at one side of the longer lever, and a stripattached to the lug and having apertures adapted to be enga ed by thepin, the said Itri Abeing insertib e edgewse through the 4 unobstructed'entrance into the space between the end of the shorter lever andl thelugr lthe nd olf'said head nearest the pin beingv a. apted to pressagainst said strip and arrange the saine in position to receive said pinwhen the levers are actua, I

Q.'A piston ring contractin device compricing handle levers pivotetogether at points between their ends, a convexed heel carried by onelever and provided near one end with a pin, a strip attached to theother lever and having a )ertures spaced at equal distances apart, an asection havin apertures adapted to be engaged by said pin, the saidsection also having spaced tongues stamped therefrom and adapted toengage in the apertures of the said strip.

8. A piston ring adjusting and contracting tool, comprising two nvotedlevers, a oontracti 'element carrie by one of said levers an consistingof a plurality of adjustably connected Section5' and means on the otherlever co-acting with said sections to contract said member.

4. A iston ring adjusting and contrectl ing tool? comprising two pivotedlevers, a flexible contractin element consisting of a main section lixeat one of its ends to one of said levers and an auxiliary section havingseparable connection with the first section and adapted for -freepassage between the adjacent ends, of both levers, the other leverhaving means (io-acting therewith to effect adJusted conditions of saidelement.

5. A piston ring adjusting and contracting tool, comprising two pivotedlevers, a flexible contracting member consisting of ii main sectionhaving a longitudinal series of peiforatioris, said section havingpermainent connection at one end with one of the levers, a secondsection having means a)adapted for interchangeable connection in theperforations of the first section, and ineens on the other leverco-iictin r with said second section to effect a drawing action thereon,as and for the pur ose specified.

In testimony whereof I a x my signature.

EMIL FRANKE.
